Toallfwhoa' may concern: Q Be it known that I, LEE CLAYTON, a citizen. of the United States, residing at Mari.- co a, in the county of Kern and State o'f Ca fornia, have invented certain new and useful Improvements in Cement Bailers, of which the following is a specification.

The present inventign relates to a device for cementing wells, when water breaks through into the well.

' One object of the invention is to provide a' device of this class,.that is of very simple construction, and which accordingly does not easily get out'of order. It is intended to convey the cement from the top of the well casing, when it is lled, to the bottom thereof and is for this purpose attached to the sand line. The bailer, after once being filled, operates automatically, that is to say,

it opens in striking the bottom of/the well and is in this manner em tied.

In the accompanying rawings, one embodiment of the invention is illustrated, and Figure 1 shows the bailer assembled to proceed in downward-direction in the well; Fi 2 is a similar view to Figure 1, showin the relative position of the parts in theuba' er, when traveling upwardly in the we Figure' 3 is a longitudinal isection along '1ine3-3ofFigure1; n

Figure 4 is a transverse section along line 4--4 of Figure 3, and Figure 5 is another transverse vsection along line 5-5 of this same figure.

' The bailer consists of -a cerner or bucket 10, which preferably is made of an iron tube closed at its bottom, as at 11. Near the bottom are provided two windows .orv delivery openin 12 laced diametrically opposite each ot er. e upper end L'of 'the bucket 10 is threaded, as at 13, and a mui 14 connects this Vend and the top or sus nding ipe 15 of the bailer. This top en has a oop 16 intended to receive the end of` a sand rope 27 for hauling the bailer up and down the well casing. Between the bucket 10 and the top member 15 may beinserted any number of tubular connections, depending on the depth A The lower end'of the bucketfl() is surrounded by a sleeve 17 adl ted to slide up and downS on the bucket. one or more helical slots 18 in its cylindrical sleeve has side, in which a stud 19 is adaptedto travel, this stud being) r'mly secured near the bottom 11 of the ucket 10, asbest seen in Figures 43 and 5. The helical slot terminates atA the lower end with a notch or ocket 20 situated in the axial plane of the s eeve and directed upwards.

S The sleeve 17 is also'provided with windows 21 corresponding to those furnished in the bucket 10 and so ositioned, .that when the stud 19vis at the bottom of the helical slot 18 the windows 12 and 21 register, while, when the Studis at the top ofthe slot 18 the windows 12 in the bucket .10 are closed by n the cylindrical wall ofthe sleeve 17 as seen lin Figure 3. i

The lower end lof the sleeve 17 is`preferably restricted, asat 22, and adapted to receive a nipple 23, threaded into the end of the sleeve. The function of this nipple 23 is to furnish a member `[for the bottom of the well and t e reason for making the diameter 'at 22 smaller than the main 'diameter of thev sleeve and the nipple still -smallergin diameter, is to permit the easy retraction of the bail from the well, as it is evident that the bottom end of the nipple, by constant hammering against the well bottom, will gradually be upset and expand. When the nipple 23 has been worn or upset too much, it may,then. be replaced'by a new.

The sleeve 17 is rovided with@ pair or r apertures 24 direct y above .the nipple lfr the passageofwater or mud, -so that t ingV up and down of the bucket 10, by this means, will not be obstructed.

The use of the bailer is as follows The sand rope'27 is tied to the loop l16 at `the upper end of the bailer and, with the latter suspended at ythe top of the well casing, the bucket 10 is. filled with cement. The sleeve 17 is nowin the osition shown in vFigures 1 and 3, closing t e windows 12 of the bucket 10 and the upper end of the helical slot 18 en aging. with the stud 19. The bailer is now owered into the well, as seen A re 1, until the nipple 23 strikes the bottomof the latter. IIhe sleeve 17 is thereby arrested and the wei ht of the bucket 1 0` together with the attac ed top 15 and the intermediaryv tubing, continues its down.-l

ward travel, while at the same tjmeereeeiving -a slight turningggnezaement-tnrougb. the acl tion of the stud 19 in the helical slot 18. When the stud 19 nears the bottom end of the slot, the windows 12 and 21 will register, thereby permitting the cement contained in the bucket to fall out through the windows. By slightly raising and lowering the bucket 10, all the cement contained therein will gradually be dumped out of the windows 12 and 21. Finall the bucket is withdrawn by pulling ont e ro e27,when it is evident that instead of following the helical slot 18, the stud 19 will travel in a perpendicular direction until engaging in the seat or notch 20 at the lower end of the slot, so that the sleeve 17, in this manner, is hauled up with the bucket 16.

- It should be noted that the distance between the mutt or collar 14 and the upper end -of the sleeve 17, when they are furthest apart, as seen in Figures 1 and 3, is slightly less than the perpendicular length of thehelical slot 18. This is, for the purpose that the stud 19 or the edge of thelslot 18 may not be injured or upset by the banimering of the bailer when hitting the bottom of the well. The adjacent faces of the muif 14 and the sleeve 17 are therefore made to come in contact before the stud 19 reaches theebottom of the slot 18,-the hammeringjv in this-manner being taken up between the two wider surfaces instead of the twc= narrow ones.

When the bailer is hauled up after de l 4 livering the cement at the bottomv ofthe weli, it is evident that water and gravel ma readil ass through the side openings 24 yurnishgdp in the sleeve 17 as well as throng-h the axial aperture 25 in the nipple 23, and that in this manner every obstruction to the free and automatic operation of the bailer is removed.

As there is nothing to get out of order in this device and as the construction is ex= tremelj,7 simple, the correct functioning of it is insured and the cost of manufacture is very low. K

At times it might be desirable to insert a coil spring 29, see Figure 3 of the drawing, in order to prevent the sliding upwardly of the sleeve 17 during the descent of the bailer .and thereby open the windows 12. With the spring 29 1n place, no such opening cani occur until the point of the nipple 23 hits the bottom.

At times, also, one or more packing rings 30 may be placed in suitable grooves in the bucket 10.' These packings fit4 snugly in the bore of the sleeve 17. Such packing rings will then prevent rthe cement from leaking into the space betweenthe sleeve and the bucket above the windows and adhering to the opposed walls so as to bind the parts together and prevent the necessa frelative movement. it' is 'evident that t e device will operate whether such pachngs and navet springs are furnished or not, but the right is reserved to include them in the construction of the device, when found necessary. The packing rings may be made of steel or, so-called hydraulicpacking, in accordance with the re uirements.

Havin t usdescribed the invention, whatv eii'ect rotation of the sleeve during axialI movement thereof, said stud being adapted to seat in said notch upon upward movenient of the bailer.
